How to reduce memory consumption on Xiaomi: speed up the system

Xiaomi smartphones are famous for their price-performance ratio, but the MIUI shell or the new HyperOS often consume a significant amount of resources, which leads to the fact that even devices with 6 or 8 GB of RAM can have difficulty switching between heavy applications. If you notice that the phone is beginning to “think” or games are starting to fly out, the problem lies in the lack of free resources.

RAM stores data from running programs for quick access, and the more processes hang in the background, the slower the system works. Unlike the permanent memory where your photos are stored, RAM requires constant management. In this article, we will discuss proven optimization methods that will help reduce the load and speed up the work of your gadget without losing functionality.

Many users mistakenly believe that the constant forced cleaning of memory through built-in utilities solves the problem dramatically.In fact, the Android system is designed to keep frequently used applications in memory for instant launch. However, on Xiaomi smartphones there are specific settings that allow you to more aggressively manage background processes and free precious megabytes for current tasks.

Current load analysis and hidden processes

Before you start cleaning, you need to understand what exactly is consuming your device. The standard task manager often shows only the tip of the iceberg, hiding system services and background processes. To get a full picture, you should use built-in developer tools or third-party analyzers that will show a real picture of RAM consumption.

You can find a section in the phone settings that shows memory usage over the last 3 hours or 24 hours. Here you will see which apps take up the most space. Often it turns out that a social network or messenger that you haven't used for several hours continues to hang in active state, consuming up to 500 MB or more. MIUI tends not to shut down such applications completely to speed up their re-launch, but this is not always justified.

Special attention should be paid to the system services of Google and the MIUI shell itself. These can take up a significant part of the memory, especially after a system update. If you see that the process of the System or Google Play Services consumes a disproportionate amount of resources, this may indicate a cache failure or version conflict, in which case it helps to reboot or clear the cache of specific services.

⚠️ Warning: Do not force system processes with obscure names to stop through the developer menu, which can lead to unstable interface operation, loss of communication, or a cyclical device reboot.

For detailed analysis, you can use debugging mode, which gives you access to more subtle settings. However, even without a computer connection, you can see the main memory eaters in the standard menu, and regularly monitoring these indicators will help you understand your phone usage habits and identify parasitic applications.

Cleaning the cache and removing system debris

One of the most effective ways to free up space is to clean up app cache regularly.Caches are temporary files that are created to speed up programs, but over time they can grow to gigabytes, taking up space in RAM and permanent memory. On Xiaomi smartphones, the built-in Security app is responsible for this.

To clean up deep, you have to go into your storage settings and analyze each heavy application. Often, a browser, YouTube or TikTok cache takes hundreds of megabytes. Cleaning up that data won't delete your accounts or logins, but it will reset your display settings and temporary files, which can temporarily slow down the first run, but free up memory.

• 🗑️ Open the Security app on the home screen.
• 📱 Select the Cleanup item and wait for the scan to be completed.
• 🔍 Click on the Garbage section for a detailed view.
• ✅ Mark unnecessary files and confirm deletion.

Also, you should pay attention to the Android/data folder, where many applications store their data. In newer versions of Android, access to this folder is limited, but through the Xiaomi file manager or third-party explorers (for example, Total Commander), you can delete the remnants of remote games or applications that are still on the system.

It is important to understand the difference between clearing the cache and cleaning the data. If you choose Clear Data, the application will return to the state immediately after installation: all accounts, settings and game progress will crash (if there is no cloud sync).

Configure memory extensions and virtual RAM

Modern Xiaomi smartphones support memory expansion technology known as Memory Extension, which allows you to reserve a portion of the internal memory (ROM) and use it as additional RAM, especially for models with 4 or 6 GB of physical RAM.

Activating this feature can improve multitasking by keeping more applications open in the background. However, it is worth considering that the speed of internal memory is lower than that of real RAM. So the performance gains in heavy games may be small, but the overall smoothness of the interface when switching between light tasks will improve.

To enable this option, go to Settings → Additional Settings → Expand Memory. Here you can select the amount of memory you add (usually 2 to 6 GB, depending on the model). Once you change the settings, you will need to restart the device to take effect.

If you have a device with 8 GB or more RAM, enabling the extension may not have a noticeable effect, and in some cases even slightly reduce the speed due to the peculiarities of writing to flash memory.

Managing Auto Startup and Background Restrictions

One of the main reasons for high memory consumption is uncontrolled auto-run of applications. In the Android ecosystem, many programs tend to run with the system to notify or update content. At Xiaomi, this process is controlled by a special service that can and should be customized.

Go to Settings → Apps → Permissions → Autorun. This will show you a list of programs that are allowed to start automatically. Leave only messengers (Telegram, WhatsApp) and important services (mail, alarm) on. Social networks, marketplaces and games can be safely turned off — they will start themselves when you open them manually.

• 🛑 Turn off autoplay for all gaming apps.
• 📉 Limit background activity for news aggregators.
• 💬 Leave auto-run only for important messengers.
• ⚙️ Check the energy saving settings for each application.

In addition, you should adjust the background activity restrictions. In the Battery and Performance menu, you can choose a power saving strategy for each application. The “No Limits” mode is only necessary for those programs that need to work constantly (for example, activity trackers or a smart home).

An effective method is also to disable unnecessary pre-installed Xiaomi services (Mi Video, Mi Music, GetApps) if you do not use them. Although it is difficult to completely remove them without root rights, you can turn off their auto-start and notification, which will reduce the load on the processor and memory.

⚠️ Note: Disabling system applications through ADB or special utilities, make sure you don't touch critical components like Security, Conductor or bootloader, which can cause your phone to fail.

Secrets of the Developer Menu for Advanced

For users who want to gain maximum control over the system, the hidden developer menu offers powerful tools. To activate it, you need to click 7 times on the build number in the About Phone section, and then a new option will appear in the settings menu for developers.

In this section, we're interested in the item "Background Process Limit," which is the default system decides how many applications to keep in memory. You can manually set a limit, such as "No More than 2 processes," which will cause the phone aggressively to unload old applications from RAM, freeing up resources for the active window.

Another useful setting is “Do Not Stay Activated.” If you turn on this option, the system will destroy the activity of the application as soon as the user leaves it, which will radically reduce memory consumption, but make multitasking impossible: when you return to the application, it will boot again, as when you first start it.

adb shell settings put global background_process_limit 2

This command can be executed through a computer with ADB installed if you don't have access to the settings menu, it will force you to set a limit on background processes, but remember that after you reboot the phone, the settings in the developer menu can reset to standard values, so you need to check them periodically.

Tip: Use the Full Screen Running feature for all applications. This not only removes black bars, but can also help the system allocate rendering resources more correctly, indirectly affecting the stability--WIDGET:tip

If software methods don't work, more radical measures are worth considering. Sometimes high memory consumption is the result of accumulated errors in the system after many updates or installing a large number of applications, in which case a complete reset helps.

Before you do this, make sure to back up all your important data, because the phone will go back to the boxy state. After you reset, you don't have to install hundreds of apps. Try using a clean system for a couple of days, and you'll probably be surprised at its speed and low resource consumption.

Also worth paying attention to visual effects: transition animations, live wallpaper and widgets on the desktop consume GPU resources and memory. In the Developer Menu, you can reduce the scale of window animation, transition and animator duration to 0.5x. This visually speeds up the interface and reduces the load on the system.

• 🎨 Remove the live wallpaper and replace it with a static image.
• 📉 Reduce the number of widgets on the main screen.
• 🔄 Turn off the gallery’s constant synchronization in the background.
• 📵 Remove unused apps completely, not just from your desktop.

In conclusion, Xiaomi memory optimization is a balance between convenience and performance. Don’t chase the maximum amount of free megabytes if it interferes with comfortable work. Proper auto-start setting and periodic cache cleaning usually solve 90% of problems without having to go into deep system settings.

💡

The most effective way to combat memory shortage is not constant cleaning, but competent management of auto-start and background restrictions for heavy applications.
